Agroup of students performed a human demonstration of a chemical reaction. jack and emily sat on a bench. kevin asked jack to leave the bench and sat in his place. which type of chemical reaction did the students demonstrate? acid-base reaction single replacement double replacement decomposition reaction

Single replacement reaction

Explanation:

Chemical reactions may be classified as replacement reactions, decomposition reactions, synthesis reactions, neutralization reactions, and precipitation reactions among others.Replacement reactions are types of reactions in which a more reaction ion or element takes the place of the least reactive element in a compound.A Single replacement reaction involves a single element taking the place of the least reactive element in a compound.A double replacement reaction involves an exchange of cations and ions taking the place of each other in the initial compound.In the above analogy, Kevin takes the place of Jack on the bench which shows how a single replacement reaction works.
